Survival Analysis and Recurrence Patterns in 555 Patients with Colorectal Peritoneal Metastases Treated by Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.
Article in Annals of surgical oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe presence at diagnosis, or development of, colorectal peritoneal metastases (CPM) is common in colorectal cancer. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) show promising results in selected patients with CPM. The current study aimed to describe oncologic outcomes of patients with CPM, focusing on recurrence patterns and risk factors for adverse events.
methodsWe conducted a retrospective review of patients with CPM treated by CRS and HIPEC at a single institution between 2000 and 2021.
resultsA total of 555 patients were included, of whom 480 (86.5%) had complete cytoreduction, with a median age of 59 years and median Peritoneal Cancer Index (PCI) of 6. Following complete cytoreduction, 5-year overall survival (OS) and disease-free survival (DFS) were 51% and 31%, respectively. In multivariable Cox regression, PCI >6 (hazard ratio [HR] 2.25), pathological node positivity (pN+; HR 1.94), and perineural invasion (HR 1.85) were associated with decreased OS, while PCI >6, pN+, and previous systemic metastases resulted in reduced DFS. Overall, 284 (62%) patients developed recurrence, of whom 97 (34%) had local recurrence (LR), 100 (35%) had systemic recurrence (SR), and 87 (31%) had combined recurrence (5-year OS: 49.3%, 46%, and 37.4%, respectively). Mutated KRAS (mKRAS) was associated with lower 5-year OS (55.8%) and DFS (27.9%) compared with wild-type KRAS (wtKRAS; 70.7% and 37.6%, respectively). In multivariable analyses, mKRAS was related to decreased OS (HR 1.82), DFS (HR 1.55), and SR (OS 1.89), but not to LR.
conclusionsComplete cytoreduction results in good survival outcomes for patients with CPM. Burden of peritoneal disease and tumor biology are the main predictors of survival. Patients with mKRAS are a high-risk cohort, with increased probability of SR and reduced survival.
